My phone screen is turning purple

[Android Central Question]

I drop my phone Alot I've had it for almost a year, but I dropped it yesterday and it was fine. When I woke up my phone was fine. But around 11 the corners of my screen were purple mostly on the bottom Right. I have another phone without a Sim card in it but when I put my current Sim card in my old phone (my first one, same Sim card) it didn't register, what do I do?!

The first will need repair. The second, I don't know, but if you mean it's not detecting a SIM, there's obviously something wrong.

Welcome to Android Central! A screen in that condition can completely fail relatively quickly, so make sure all of your important data is backed up or synced somewhere NOW.

Have you ever tried that SIM in your older phone? If that phone was from a different carrier, the SIM might not work (because the phone could be carrier-locked, or it might not support the network bands that your current carrier uses).
